I have an extremely positive review of the Crossbow family, but I am biased. FWIW...
I wanted the Crossbow frames/lenses for a while, but put it off due to budgeting and just shot using a cheapie pair of safety glasses. Not too long after buying the Crossbows, I was hit in the face with part of a bullet that bounced back, and the lens absorbed all of the energy. While the lens was obviously ruined, it did not break. Had I been wearing the cheaper pair, I think there is a chance I would have lost an eye.
Beyond the impact resistance, I like how the Crossbow lenses are designed to cover all of the eye area without any gaps above/near the eyebrows, or below/near the cheek bone. I feel this reduces the chance that a bullet fragment that hits right below or above the eye can skip through one of these gaps and go right at or into the eye. A Wiley pair I had (which I also really liked) used this same no-gap lens design.
If you wear muffs, my vote is to get the Suppressor. It's the most comfortable frames I have used with ear muffs and my a significant margin. The first thing I noticed the first time is that they NEVER shift while wearing ear muffs, even if the positioning of the ear muffs themselves shifts. I'm yet to use another frame I can say that about.
However, for times when you shoot without muffs on, you may want another frame because the Suppressor absolutely must be used either with muffs or with the included strap (tightened tightly), as the thin profile and lack of angles that make them so comfortable with muffs will slide without having one of those two things to hold them in position. Luckily, you can get the Suppressor and one of the other frames in the family and use the same lens for each frame.
For me, the Suppressor is used most with yellow lens' for indoor shooting, as I prefer to wear both muffs and ear plugs due to the increased sound shooting indoors, and a Crossbow Elite I use when shooting outdoors, almost always with the copper lens'. I personally find yellow enhances contrast indoors much better than clear, and copper provides dramatically better contrast when shooting outside, but still enough light reduction that I use them for all outdoor shooting except when I am fully exposed and the sun's position is directly in my line of sight (in which case I use the darker smoked lens'.)
But thanks to keeping the commonality of lens', I could pop my yellow lenses into the Crossbow Elite if I am shooting outside and then sun goes down to a point where I want more contrast, or pop the copper lens into the Crossbow Suppressor should someone be shooting a super loud gun next to me at the range, where I will want to add muffs in addition to the ear plugs.
If I could go back in time, I probably would have purchased the polarized darker lens. It might be because all of the sunglasses I wear are polarized, in direct sunlight I see a huge difference between the non-polarized Crossbow smoke lens versus my Revo sunglasses. Especially if I am facing something in direct sunlight with a bad glare, I really regret it...so one day I may have to drop the cash on it.
